As I am currently in the process of being discharged from medium-term residential medical rehab, I almost forgot my old custom on December 26!

Anyone with Roman Catholic, "Old" Catholic, "High-Church" Protestant, or Eastern Orthodox Christianity in hir background knows what December 26 is: it's the Feast of Saint Stephen, Martyr (see Christian Scriptures, Acts of the Apostles, 6:8 -- 7:60 inclusive).
